Special Mossad
agents are working together with Bulgaria's
national security agency (SANS) to beef up security in sites frequented by Israeli tourists in the country, the local Standard News website reported Friday.

Quoted by other media outlets, the report said that the steps were taken ahead of Rosh Hashana.

Bulgarian website Novinite noted that the date in which Rosh Hashana is marked, September 17, falls on St. Sofia Day.

According to reports, security has been beefed up in and around synagogues, hotels and even churches. Agents will also oversee traffic at airports in Sofia and Burgas, where a terror attack
claimed the lives of five Israelis and one Bulgarian citizen in July.

The Bulgarian reports stressed that Israel's Counter Terrorism Bureau
did not issue a Bulgaria travel advisory. It did however ask authorities in the country, as well as in Thailand, Greece and Cyprus, to increase security measures around Israeli tourists ahead of the High Holidays.

Israeli defense officials are also monitoring the investigation being conducted by Bulgarian security forces into the Burgas attack. Bulgaria has beefed up security around Israeli tourists, they said, but not to the required level.

The CTB made it clear to Bulgarian authorities that the fact that a terror attack had already taken place in Bulgaria does not a guarantee that an additional attack would not take place there again.

The CTB stressed that it was very important on a diplomatic level that the Bulgarian investigation points to Hezbollah as being directly responsible for the attack.

Such a declaration could lead to Hezbollah
being declared as a terrorist organization, a step the European Union still refuses to take.
